[12.13] Stellar Populations in the Southeast Part of the Small Magellanic Cloud from HST/WFPC2 Imaging

S. R. Shaffer, D. R. Garnett (Univ. of Arizona)

We present a new color-magnitude diagram of a field in the
southeast part of the main bar of the Small Magellanic
Cloud, near the H II region N12A. The CMD is based on
imaging with the WFPC-2 camera on the Hubble Space
Telescope. VI photometry of stars in this field was
performed using HSTphot. The photometry is 80% complete to
V and I magnitudes of 22, or M(V) = +3. We have analyzed the
CMD taking into account the spread in distance modulus for
this part of the SMC (based on the spread in distance of
Cepheids within 30 arcmin of our field), and the reddening
toward the field. The CMD in this field is very similar to
the CMD obtained by McCumber, Garnett, & Dufour (2005) for
a field in the east wing of the SMC, although the mean
distance and distance spread are slightly larger, and the
average reddening is also slightly larger in the N12A field.
We will present results of Monte Carlo simulation of the
star formation history of this field based on our CMD.
